@furgar Yeah, it seems NO one has heard of this besides the one person in the video, who happened to be filming, and happened to be the only other person on earth to know this "sign" and somehow 2 OTHER women also knew exactly how to set up and execute a plan to help in a few seconds, and left the man looking foolish, spinning around.

It sounds like someone trying to "make 'fetch' a thing." They made this up. Not that it isn't helpful, I guess.
